Speaking at an FX press conference for the show, Hawley admitted that "conversations are being had" about whether the series could return.

"Obviously in an industry like this, any time something is a success, you think how can I make more money off of it," he explained.

"That said, my experience with FX is they're very proud of the quality of the work, and their biggest concern is if we were to do it again, could we make it as good or better, and certainly those are conversations that are being had.

"I think that, for me, it's really important that there's a kind of alchemy that happens when you get all the right elements in place.

"A lot of it is skill but some of it is luck as well, and I'm not in any hurry to try to top myself there. I'm excited about the idea of really taking the time to think about [it all] and the network is kind enough to allow me to do that."

When asked if he had any plans for potential second season plots, he added: "I have some thoughts of what we could do that I think would be really great, but... I don't want to just have an idea for how it starts; I need to have an idea for how it ends.

"It starts and ends in the same season, so you can't fake it until you make it. You have to start out knowing exactly where you're going."

One cast member who will not be returning to Fargo if a second run gets the go-ahead is British actor Martin Freeman, who plays insurance salesman Lester Nygaard.
